Interference of Wing and Fuselage from Tests of Eight Combinations in the NACA Variable-density Tunnelcombinations with Tapered Fillets and Straight-side Junctures

The round fuselage of an unfilleted low-wing combination was modified to incorporate straight-side junctures. The resulting combination, with or without horizontal tail surfaces, had practically the same aerodynamic characteristics as the corresponding round-fuselage tapered-fillet combination.
